Body Fat Percentage - 3 Site SkinFold Calculator

To use the 3 site skinfold calculator measure the skinfolds when the skin is dry, before exercise, and when you're not overheated. Measure each skinfold 3 times and use the 2 which agree. Pinch from the top and measure from the bottom. (Directions to take skinfolds are given after the calculator.) This will allow you to determine what are high skinfolds.

Enter the skinfold values in the tables below and press 'calculate body fat'.
